Oh, so that was a game. I got pretty close. I said, "That 280 must be advertised duration. So it must be in the 212-220 range at .050 depending if the specs were .004 or .006. I think the lower range is correct and maybe that is a tad high."
The 212-220 I was referring to was cam duration at .050. The lower range was correct.
OK, let's play again!
